| 中文摘要: |
| 采用正交试验方法对硝酸锌、钼酸钠、三聚磷酸钠进行复配,得到一种适合于不锈钢在酸性高锰酸钾去污溶液中的优良缓蚀剂,利用失重法、电化学测试、微观表面分析等手段对其缓蚀性能进行了评价。结果表明:该复合缓蚀剂是一种阴极型缓蚀剂,适宜于常温下去污,缓蚀率达到97.40%;溶液的高速流动对其抑制基体腐蚀的能力没有影响,使用该缓蚀剂后,金属表面腐蚀非常轻微,无点蚀及晶间腐蚀等非均匀腐蚀现象。 |
| 英文摘要: |
| A composite inhibitor of stainless steel in acidic potassium permanganate decontamination was prepared by orthogonal method. Its property of inhibiting corrosion was evaluated by weight-loss method, electrochemical test and surface analysis. The results show that the compound inhibitor is a kind of cathode type inhibitor. It is well used in normal temperature and inhibition efficiency reach 97.40%.It is very little that high-speed flow of liquor impact on restraining the ability of matrix corrosion. The photos of metallurgical microscope and electron probe indicates that signal of heterogeneous corrosion is not found under different corrosion condition. |
